Sythetic Flashpup Adventure Started

The shroud is 20mm x 17mm CF tubing. The moderator is home brewed made from a Maglight flashlight with a stack of 8 air strippers inside.

Here's a picture. Works much better than the factory unit.

Cool!

Are those baffles the ones for sale on Ebay?

It's a great idea., I have one I bought from China, very well made, monoblock. Looks kinda like yours.

Yes they are the same ones from Ebay. I just fitted it into the Maglight body and they work better than in the factory shroud which really doesn't allow it to breathe very well with onlt one little air escape hole back near the plastic mount for the optics rail.

Very stiff tube and the tensioned barrel on the WFP is marginally better than the bonded SFP due to tension. When you pinch the joint at the breach block and torque on the barrel the tensioned barrel has no shifting you can feel with finger tips. The bonded barrel has very slight motions at the barrel insertion to breach block since there is only the set screws and carbon sitting adjacent with no tension . I'll be slipping a 20x19 tube over it, tensioning and loose the shim. I would try tensioning the largest diameter tube I could fit on the Turkenstein, functions like a truss.

Hey, Thane.

As you know, (and have posted there) there is now a new thread devoted solely to CF sleeves:

Donny, it would be great if you could also comment there, if you have any new thoughts or ideas.

Regarding the pint Thane makes in the quote, above:  This is very good to know.  I will be adding a very tight sleeve to my wood Flashpup, so I'm thinking of gluing a few washers to the breech-end. I figure that will help stiffen the joint in the same way that the wider diameter tube does.
Maybe I can get one of you guys to make me a couple of derlin washers?   

 -  Of course this will only works if the tube will be loose enough to slide over the barrel.  I did manage to find a likely contender (referenced in that other thread) which is a tad wider ID than 14mm, at 0.555,  so we'll see.

Also note:  One thing no one seems to have mentioned is that there are several different types of CF tube construction, and some are stiff than others.  I'm no expert, but I know that pultruded is one of the stiffest,  and high modulus is probably the ultimate.  -  SadlyI couldn't find either with the perfect ID,  so I went with "uni roll" construction, which is still said to be fairly stiff.  It's not very thick, though, but I figure that doesn't matter if it's going flush against the barrel.  For a wider tube (basically a shroud replacement) it would probably be best to find one of the stiffer types.

There is also a type that is NOT stiff at all, and it kind of looks like the type Thane used.  ( ! ) - but the high modulus looks very similar, so maybe he got the good stuff. (It's very expensive, though.)

Yep.  That's the monocore type, sold by GEOFF and others.   They work amazingly well.

I used rolled construction.
the larger OD fits better in the rail risers and the thick 3mm side walls are very stiff.
